Patented April 16, 190'7.

Application filed May 31, 1906. Serial No. 319.538.

To all 110mm/ f/r Wt/ny/ concern:

Be it known that I', JOSEPH Ml STORY, a citizen 'of the United States,residing at Owosso, in the county of Shiawassee and State of Michigan,have invented a new and useful Steam-Generator; and I do hereby declarethe followii'lg` to be a full, clear, and eXact description of theinvention, such as will enable others skilled -in the art to which itappertains to make and use the same.

This invention relates to certain new and useful improvements insteam-generators, the invention havin for its object to provide anapparatus of t iis character having a boiler disposed. upon a verticalplane, through which a vertically-disposed combustion-chamber or tubeextends, by which the water within the boiler is heated to a capacitysufficient to generate steam, which passes upward to the dome. Freinthence it is conveniently utilized for the purpose desiredthat is, whenthe tube-igniter causes a combustion`through the intermittent verticalcircuit-breaking bolt, which is operated by means of the cam carried bythe driving-shaft of the apparatus.

The usual gasolene-tank is provided, to one side of which the carbureteris positioned for the purpose of generating gases which are conveyed tothe gas-pump. t rough the cooperation of the motor which is beltedthereto, from which gas-pump the gases are forced into thecombustion-chamber through an intermittent entrance which is operated bythe driving-shaft coperating with a secondary shaft.

This invention comprises further objects and combinations of elements,which will be hereinafter more fully described, shown in theaccompanying drawings, and the novel features thereof will be pointedout by the appended claim.

To obtaina full and correct understanding of the details ofconstruction, combinations of features, elements, and advantages,reference is to be had to the hereinafter set forth description and theaccompanying drawings in connection therewith, wherein` Figure l isavertical sectional View through the boiler and combustion-chamber,showing also in conjunction therewith in a diagrammatic way theosolenetank, carbureter, and gas-pum Ti-g. 2 is an end view showing morefully the general contour of the boiler and steam-dome. Fig. 3 is a viewshowing an inclined boiler of a size considerably larger than shown inFig. 1,` so as to accommodate a plurality of combustion-chambers, eachhaving the usual igniter.

Making renewed reference to the accompanying drawings, wherein similarreferencecharacters indicate corresponding parts. in the severalillustrations, by figures, 1 designates the boiler, which is ellipticalshape in cross-section and circular in end View, in

'which-is positioned the combustion-chamber 2,'having the outlet-valves3 for the escapement of the gases of combustion. Positioned above theboiler is the steam-dome 4, to which the steam rises, from which it isconveyed when desired for use by means of the pipe 5, which is providedwith a regulating-valve 6, as clearly shown.

The outlet-valves 3 are seated upon the sides of the combustion-chamberor eXplosion-chamber within pipes a, which extend laterally from theexplosion-chamber through the walls of the boiler, which are providedwith lands or packing-boxes 3b, in which suitab e packing is placedaround the pipes a, so as to form tight joints. The pipes aare providedwith elbows and with upward eX- tensions, through which the gases ofcombustion may be conveyed to the point of discharge. Within the pipes aare crosspieces or bridges 3c, affording bearings for the stems 3d,carrying the valves 3, which latter serve as closures for the ports 4bin the side walls of the explosion-chamber. The valves 3 are normallykept closed by the action of suitably-arranged springs 40. When thetension of said springs is overcome by the pressure of the gases in theexplosion-chamber, the valves 3 will be displaced by the pressure of thegases, which latter will thus be permitted to escape until equilibriumof pressure is restablished.

The combustion-chamber or explosionchamber is suitably raised andsupported within the boiler, as clearly shown in Fig. 1 of the drawings,by means of bars or brackets 7.

The gases are drawn into the gas-pump 8 on the upper stroke of thepiston 8*that is, after they have been generated by the carbureterSZ-through the pipes 9, and upon the downward stroke of the piston thegases are forced into the combustion-chamber 2 through the pipin 10,which piping is rovided with suitab e check-valves 10', w ich piping l0is connected to the gas-entrance pipe 11 and also affords communicationIIO to the combustion-chaiuber, as wil-l be understood. Thisgas-admitting' valve is reseated by means ol the spring 13, which ismounted upon the stem ol the valve between the nut 13 oi thepacking-gland 132 of the gas-entrance pipe and an onlin-gement 111 uponthe end of said stem, which enlargement travels within a groove 15 ofthe cam 16, which is mounted upon the secondzu'y shaft 17, which isjournaled in suitable bearings 18, as clearly shown. This s xeco'l'idaryshaft is operated through the i'nedium ol the belting 19, which travelsover the pulley 2() oi" the said secondary shaft and the pulley 21,

carried by the shaft ol' the gas-pump, as.

clearly shown in Fig'` l. .lhe driving-shaft of the gas-pump is suitablyonerated by means of the pulley 22, journaled to said. shaft, which isbelted to the motor 23, such as shown, but which may be of any suitablety e. Positioned above the gas-admitting v ve 12 within the gas-entrancepipe is a a check-valve 24 to prevent the retrogression of the gases.Water is supplied to the boiler throufrh the pipe 20', which is providedwith a re u ati-n -valve 25, as shown.

T e com ustion-chamber is provided with a tube-igniter 26, which iselectrically connected with the plates 27, having the contact-points 28,one of which plates is suitably secured to a horizontal portion 29 of avertically-extending arm 30, projecting from the u per part of thegans-pump, and thev other ate 27 is suitably secured to an oscillatingliever 31, which is pivoted to the said arm 30. These plates 27 aresuitably insulated from the metal to which they are secured and areelectrically connected with the tube-igniter by means of the wires 32,having a suitable batter 33 in circuit therewith. rlhis oscillating everis operated by means of the vertically-movable bolt .34 and the groovedcam 35 in conjunction therewith, which is journaled uJon the shaft 0ithe gas-pump, as clearly yustrated in Fig. 1 of the drawings.

By means of the construction just described an' intermittent movement isimparted te the oscillating lever 31, se as to form electricalconnections at regular intervals between the contact-points 28, thusbreaking the circuit and causing the tube-igniter to be operated, afterwhich a combustion of the gases is rendered by which thecombustionj'ehamber is coiisiderably heated, thus causing' the waterwithin the boiler to be gradually heated, from which the steam arises tothe dome 4, as will be understood.

'lhe piston ol' the gas-pump is comiected with the driving-shalt thereofby means o'i" the pitman 36, as clearly shown. The apparatus is providedwith a gasolene-tank 37, having' suitable conl'iection and communicationwith the carburetor 82 through the pipe 9. The pipes 9 are provided withclieck-valves 3S, which open upon the. upward stroke of the piston ei"the gas-pump, so as to draw the gases thereinto, and upon the downwardstroke oi the piston the said clieffk-valves are closed and thecheek-valves 10 of the piping 1() are open, thus allowing the to enterthe combustiou-chaiuber when the gas-admitting valve is open.

.ln Fig. 4. is shown a boiler of su'l'licient size to Vaccommodate aplurality of combustionchamliiers which. are supplied with gases by butnot being necessary to be shown in conjunction with the constructionshown in the said Fig. 4.

From the foregoing the-essential features, elements, and the operationof the device, together with the simplicity thereof, will be clearlyobserved and when manufactured in accordance with the invention aninexpensive market will be easily obtained therefor.

Having thus described the invention, what is claimed as new and usefulby the protection of' Letters Patent is- In a steam-generator of theclass deported within the boiler, means for intermittently admittingexplosive-gases into the explosion-eliamber, interniittently-operatingmeans for igniting said gases, escape-pipes connected with theexplosion-chamber and extending through packing-glands in the Walls ofthe boiler and sprlng-actuated'escape-valves within said pipes normallyengaging escape-ports in the side walls of the combustion-chamber.

In testimony .whereof I have signed my name to this speciiieation in thepresence of two subscribingl witnesses.
